How does PRP for hair loss work?

A small blood sample is processed in a centrifuge to separate platelet-rich plasma from other blood components. The clinician then injects the prepared plasma into areas of thinning or reduced density. Platelets contain signalling proteins involved in wound repair, so the aim is to improve the follicle environment and support the growth phase of some hairs. PRP may be considered for selected pattern hair loss, but sudden shedding such as telogen effluvium needs its trigger assessed first.

Before treatment, share your medical history, scalp symptoms, medicines, and any bleeding or platelet disorder. Your clinician should examine the pattern of loss and discuss whether PRP is appropriate alongside other treatments. After injections, mild tenderness, swelling, or pinpoint bleeding can occur. Keep the scalp clean as instructed, avoid vigorous rubbing, and follow guidance about exercise, hair products, and pain relief.

Contact the clinic for increasing scalp pain, spreading redness, warmth, pus, fever, or a reaction that is getting worse rather than settling. Seek evaluation for rapidly progressive loss, smooth patches, scalp scaling, scarring, or hair loss with other body symptoms. These features can indicate a condition that needs a different investigation or treatment.

Ask what type of hair loss you have, how the plasma will be prepared, where injections will be placed, how progress will be assessed, and which proven options can be combined with or considered instead of PRP.
